    nfit, libnvdimm: clarify "commands" vs "_DSMs" · e3654eca
    Dan Williams authored
    Clarify the distinction between "commands", the ioctls userspace calls
    to request the kernel take some action on a given dimm device, and
    "_DSMs", the actual function numbers used in the firmware interface to
    the DIMM.  _DSMs are ACPI specific whereas commands are Linux kernel
    generic.
    
    This is in preparation for breaking the 1:1 implicit relationship
    between the kernel ioctl number space and the firmware specific function
    numbers.
